Research on Space-Variant Baseline Error in Micro-Deformation Monitoring Radar

Due to external factors or inherent equipment limitation, micro-deformation monitoring radar will introduce the spatial baseline errors phase to the measured results. This paper proposes a method to estimate and compensate the space-variant baseline error phase for this problem. This process mainly uses total differential and singular value decomposition method. The final experiment proves that our method performs well in correcting the phase of space-variant baseline error caused by equipment vibration and helping the accuracy of deformation inversion improved.
